Therefore, the following description will be given with reference to FIGS. 1 and 2.

First, the sensor unit 140 detects that the tray roulette R is exposed or inserted outside the optical disk changer system (S1). The sensor unit 140 provides a high signal to the controller 20 when the tray roulette is exposed to the outside of the optical disk changer system, and provides a low signal to the controller 20 when the tray roulette R is inserted into the optical disk changer system. do. When the tray roulette T is exposed to the outside of the optical disk changer system, the user can mount the disks D to be watched on predetermined trays T of the tray roulette R.

Next, when the control unit 20 receives a low signal from the first sensing unit 140, the control unit 20 may select a disk D to be viewed by the user from among the disks D mounted in the tray roulette R. Is selected (S2), if a predetermined disk (D) is selected, the control unit 20 controls the tray roulette driving unit (R) to reach the chucking position. When the disk D selected by the tray roulette driver R reaches the chucking position, the controller 20 controls the optical pickup unit 30 to optically pick up the TOC contained in the disk D and output the RF signal.

The RF signal is amplified by the RF signal amplifier 40 based on a predetermined degree of amplification, and then processed by the digital signal processor 50 as a digital signal to the controller 20 (S3).

When the TOC of the selected disk D is read in step S3, the controller 20 determines the ID of the disk D as the total number of tracks of the selected disk D (S4) and searches the storage unit 130. It is determined whether the corresponding ID is stored (S5). As a result of determination, if the corresponding ID has not been previously stored, the controller stores the corresponding ID in the storage unit 130 (S8), and if the corresponding ID is stored in the storage unit 130, the corresponding ID corresponds to the corresponding ID. The name of the previously input disk is detected (S6). Then, the OSD unit 150 displays the disk name on the monitor 100 under the control of the controller 20 (S7).

However, if it is determined in step S5 that the ID of the selected disk D is not stored, the OSD unit is configured to construct a menu screen for inputting the name of the selected disk D after storing the ID in the storage 130. Control 150. When the OSD unit 150 displays a menu screen on the monitor 100 under the control of the controller 20 (S9), the user inputs the name of the selected disk D. For example, if the selected disk (D) is 'animal kingdom 3 house', the user may enter the name 'AML3'.

As such, when the name of the selected disk D is input, the controller 20 determines whether the disk name input completion signal is provided through the key input unit 10 (S10), and if the disk name input completion signal is not provided, the control unit 20 continues. And display a menu screen through the monitor 100 and, conversely, when a disk name input completion signal is provided, the controller 20 displays the name of the disk input by the user on the monitor 100 through the OSD unit 150. do. In addition, the control unit 20 stores the name of the disk input by the user in the storage unit 130 corresponding to the ID of the disk D (S11). Therefore, if the disc D in which the name of the disc is stored is reproduced in step S11, the disc name will be displayed on the screen by the above-described steps S3, S4, S5, S6, and S7.

As described above, the display method according to the present invention has an advantage of identifying each type of disc by giving a name to each disc when a plurality of discs are mounted in the tray roulette.
